Abstract

PURPOSE:To improve producitivity and quality by automatizing cutting and supplying work of a carcass ply. CONSTITUTION:A carcass ply CP is sent out of a festoon section Q-1 with a second conveyor 64 and halted at specified counts after the tip of the ply passes below a detector 74. Then, it is wound with a roller 63-a being pressed on a drum M while the detector 74 continues to count and the drum M and first and second conveyors 63 and 64 are halted at specified counts. As a lift frame 93 lowers, a cutting blade 103 runs to cut a rubber section between steel cords of the carcass ply CP. As the drum M and the first conveyor 63 are operated synchronously again, only the carcass ply on the first conveyor 63 is wound on the drum M to complete a carcass ply band. Then, released from the pressing on the roller 63-a, the drum M moves from the X' position to the X position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tire material cutting and feeding device.

2. Description of the Related Art During the radial tire manufacturing process, the apparatus shown in FIG. 1 is known as a first stage apparatus of a two-stage molding system for assembling tire components to form a green tire. This device consists of an expandable band forming drum (a) for enclosing the constituent parts of the bread K (CB) when forming a carcass band (CB), a rotating device for the drum (a), and an expanding/contracting device. , and a crimping device for crimping the materials on the tram. After receiving the band transfer (d) that grips and transfers the band (CB) from the outside, the movement trajectory tel of the transfer (dl), and the band (CB) transferred by the transfer (d), the beat 9, Lean case forming drum (f) that can be expanded and contracted for assembling structural members such as walls
, a head 9 stocking device (g) equipped with a rotating device and an expanding/contracting device for the same drum (f), a crimping device (h) for the material on the same drum (f), and a beat 9 set, ply down, and turn up device. A plylock device (j) on the headstock (g) side for work, a plylock device (j) for the same work on the opposite side of the head stock, and a movable tailstock with the same device (j) installed. The device (hl) and the drum (
A thin rubber sheet called an inner liner is automatically fed out from the material supply device (c) to the ram (a), and an automatic automatically cut, automatically wrapped, and automatically joined. After that, carcass ply (cp
) is sent out from the supply device (c), cut, wrapped, and joined to complete the carcass band (OB).The completed carcass band (CB) is transferred to the drum (f) by the transfer (dl). ) and then automatically handed over to the drum (r).
f) The upper carcass member)' (CB) is 1 to 9 ram (
After the both ends of f) are automatically plyed down, the bead is automatically set, and turned up automatically, the sidewall etc. are sent out from the material supply device Ce), wrapped once, and automatically The IJ-container case (GC) is completed. Furthermore, the completed green case (GC) is automatically removed from the drum (f) and transported to the second stage device.

When forming the carcass ply (OB), the operations of feeding, cutting, winding, and joining the carcass ply (CP) are performed manually by an operator. The reason for this is as follows. That is, when cutting the carcass ply,
The cutting length is determined by the rotation speed of the drive roller of the conveyor that moves the carcass ply, or is detected by the rotation speed of the length measuring roller of the feed amount detector that touches the carcass ply, and the cut length is stopped. Since the method of cutting the conveyor later is adopted, when the conveyor moves, the drive port, -
The cut length may be incorrect due to slipping between the carcass ply and the conveyor belt, between the conveyor belt and the carcass ply, or between the carcass ply and the length measuring roller, or the ply may be misaligned on the conveyor belt. The amount of overlap may be less than the amount of overlap, or even there may be no overlap (1,
Lacks stability.

Also, even if the specified cutting length can be measured accurately, there is a high probability that the cord will reach the cutting position, and if the cord is a steel wire cord (piano wire), the cutter may be damaged.
The carcass ply of a radial tire, which can disrupt the cutting length, is an important strength member of the tire sidewall, and the lack of overlap could cause a serious accident. Therefore, the inner liner is wound on the ram (dl) and joined to complete the inner liner, and then the carcass ply is wound and joined to complete the carcass band. Even if the gluing and joining work was automated, the time required to form the carcass band could not be shortened, resulting in a decrease in productivity.

The present invention addresses the above-mentioned problems, and includes a first conveyor and a second conveyor that are connected to each other for transferring the carcass ply, a carcass ply cutting device that is installed between each conveyor, and 1st Koni/-! a suction device that suctions the cut end of the carcass ply and moves in synchronization with the second conveyor while the vehicle is stopped, and the cut end is transferred onto the first conveyor by the suction device. a tire material cutting and supplying device characterized in that the first and second conveyors are moved synchronously, and a first conyer and a second conveyor that are connected to each other and that transfer the carcass ply;
A carcass ply cutting device installed between each of the conveyors detects the number of cords in the carcass ply transported by the conveyor, detects the cut length of the carcass ply, stops the conveyor, and operates the cutting device. and a suction device that suctions the cut end of the carcass ply while the first conveyor is stopped and moves in synchronization with the second conveyor, and the suction device moves the cut end of the carcass ply to the After being transferred to the first conveyor,
The tire material cutting and supplying device σ is characterized in that the first and second conveyors are moved synchronously, and its purpose is to automate the carcass ply cutting and supplying operations, thereby increasing productivity. Another object of the present invention is to provide a tire material cutting and feeding device that can improve quality.

It can be anything. As shown in FIG. 10, the Naori-Cusply (CP) has a convex portion including the steel cord and a concave portion between the cords. Then, after the most advanced steel coat (sc) of the carcass ply (cp) cut by the automatic cutting device (Pl, described below) passes under the detector σ, the steel coat 9 is cut by the above-mentioned method. The first conveyor stops when it reaches the tip roller (63-a) section.When it reaches the tip roller (63-a) section, the preset count number is counted. The count number N1 is determined by the distance Ll between the roller (63-a) and the detector σ slope, and the pitch of the steel cord is N-1°. Established.

While the main carcass band (CB) is prepared (N+2), the main green case (GO) is completed on the drum (f), and tires are continuously produced. In this example, the drum (f) is used as the green case forming drum of the first stage device in the two-step forming method, but if it is made into an inflatable drum device as described in Japanese Patent Publication No. 55-35256, two It can also be applied to step molding methods.

The tire material cutting and feeding apparatus of the present invention is configured as described above, and has the effect of automating the carcass ply cutting and feeding operations and improving productivity and quality.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design changes can be made without departing from the spirit of the present invention. .
